Mark Collins, DO

Mark Collins’ DNA. The weaknesses Dr. Collins witnessed in inpatient mental health and rehabilitation facilities combined with a lack of personal connection between staff and patient helped him realize that big pharma and large facilities needed a more complete and comprehensive approach.

During a neuropsychiatry fellowship in 2012, Dr. Collins learned more about the brain and differential diagnoses that could lead to better solutions.

“We are on the verge of a huge change in psychiatry. TMS, neurofeedback, and ketamine are game changers – a true paradigm shift. We have to evolve what we do so we are not causing more harm than good.”

Dr. Collins has been practicing psychiatry for over 25 years, currently, a triple board certified psychiatrist. He was determined to become a doctor since junior high school. What was initially a plan to go into primary care, a revolution in psychiatry during Dr. Collins’ med school days prompted him to explore this field specifically, with guidance from a well-established mentor.

While in his second year of residency, Prozac became the go-to mental health drug, with the school of thought that it would be a “cure all.” Dr. Collins recognized there was far more to mental health care than a “one-size-fits-all” medication. His extensive understanding in the diagnosis and treatment of mental illness and substance abuse motivated him to specialize in co-occurring disorders.

Dr. Collins provides cutting-edge, innovative clinical treatment in a non-research university setting. By utilizing a small hospital with personalized care, he is able to focus on in-depth evaluation and treatment of the brain, specific to each patient. It’s this type of individualized attention that makes StoneRidge exceptional.
